1. A receiver/transmitter device for logistics tracking configured to monitor or detect at least one shipment unit, comprising:
at least one cellular transmitter for transmission of wireless signals via a cellular network;
at least one ultra-wide band (UWB) transmitter for transmission of radio signals over a short-range network;
at least one radio frequency identification (RFID) reader configured to detect at least one passive RFID tag associated with the at least one shipment unit;
at least one processor in communication with the at least one cellular transmitter, the at least one UWB transmitter, and the at least one RFID reader configured to:
selectively cause the at least one cellular transmitter or the at least one UWB transmitter to wirelessly transmit information detected by the at least one RFID reader to a remote computing device or computer server,
receive location information based on signals received by the at least one UWB transmitter and/or the at least one RFID reader, and
cease communication via the at least one cellular transmitter when the location information indicates that the receiver/transmitter device is within a facility including a UWB and/or RFID gateway; and
a housing configured to be mounted to a transport platform that encloses the at least one cellular transmitter, the at least one UWB transmitter, the at least one RFID reader, and the at least one processor.
